PROBLEM TO BE SOLVED: To securely seal a packing material without impairing the external appearance.;SOLUTION: A pillow packing machine includes a center seal apparatus 12. The center seal apparatus 12 seals both end edges of a belt-like packing material in a width direction, in which cylindrical bag-making is performed in a continuously conveying process, as a center seal part by making the packing material pass through a space G, which is formed by a pair of heating seal faces 14a, in a state of being overlapped with each other. A pair of the seal faces 14a are curved surfaces that become concave and convex along the conveying direction.;COPYRIGHT: (C)2014,JPO&INPIT
